v26.8.5 - 📑 A new Per-device Change log and various fixes

Hi all 👋

I’ve focused this release on improving visibility into system activities and ironing out friction points in multi-node and notification workflows.

A major addition in this update is the new Change Log view, complete with dedicated filters, grouped change entries, and history retention settings to help track state changes over time. I’ve also expanded notification templates and placeholders to support VLAN, site, and SSID data, alongside updating the underlying settings to gracefully handle multiline text.

On the reliability side, I've addressed several edge cases in core integrations and syncing. This includes fixing a silent failure where device data wasn't being sent in SYNC push mode, resolving issues with NEWDEV IP/MAC ignore rules failing to exclude local entries, and implementing critical Telegram plugin execution hardening thanks to reports from @tyr4n7 and @tonghuaroot.

I’ve also resolved data handling papercuts - such as fixing DataTable timezone-trimmed timestamp sorting, ensuring webhook payloads are serialized consistently for accurate signatures, and correcting an issue where UNIFIMP repeatedly overwrote device IPs with an invalid 0.0.0.0 address.

Thanks for the ongoing support, bug reports, and contributions.

Please note the Breaking Changes section, especially as I plan moving plugins directory from /front/plugins to /server/plugins if you have some custom built plugins or modifications mapped in your docker-compose.

Now onto the changes.
